I prefer stainless and have used Julien sinks in 2 kitchens and been happy with them. Can't go wrong with a good quality stainless sink.

Think about location of the drain too.

Mine: Julien 30" sink with 18" integrated drainboard and right rear drain.

I also prefer stainless. I looked for sinks in 16 gauge SS (it's thicker than 18 gauge) and with sound-dampening coating on the bottom.

Mine is a Rohl Forze 31.5". It has square corners and I like the look, but they can be a pain to keep clean. Many here recommend the sinks with rounded corners and I can understand why. I don't have a brand recommendation for the rounded corners, but I'm sure others here will.

One of the regular contributors here, @Joseph Corlett, LLC, is widely considered to be an expert on sink installation. He recommends using a strap system like Sink Strap or the Hercules Universal Sink Harnesses.

When it comes to composite sinks, the Elkay Quartz Luxe is much finer than Blanco.

Yes, strap your sink, please.
